Rigetti Computing announces launch of 84-qubit Ankaa-3 system

Rigetti Computing (RGTI) announced the public launch of its 84-qubit Ankaa-3 system. Ankaa-3 is Rigetti’s newest flagship quantum computer featuring an extensive hardware redesign that enables superior performance. Rigetti also celebrates major two-qubit gate fidelity milestones with Ankaa-3: successfully halving error rates in 2024 to achieve a median 99.0% iSWAP gate fidelity, as well as demonstrating 99.5% median fidelity fSim gates. Ankaa-3 is now available to its partners via the Rigetti Quantum Cloud Services platform and will be coming to Amazon Braket and Microsoft Azure in the first quarter of 2025. Users will be able to operate these higher fidelity and universal iSWAP gates for a wide range of algorithmic research, with a median gate time of 72 nanoseconds. The faster, more specialized fSim gates are useful for specific algorithms such as random circuit sampling, as recently demonstrated on Google’s Willow system.
